Diversity Hire   Originally a person hired to fill a quota, mostly by companies sufficiently large to be targeted by "civil rights" organizations for not hiring enough Afram or female employees. Ideally it would be a female Afram, inflating the statistics by counting the same person twice. This was expensive as normally a qualified employee (white male) was needed to actually get the work done. A diversity hire has to check more boxes, so a physiclly female alphabet person is chosen. Actual qualifications are even lower than the old quota-filler, often mere sentience is as far as it goes. So one or more normal people are employed to do the work and clean up the mess made by the diversity hire.
